Net assets are what it owns minus what it owes; management and general is office, admin and insurance cost. A dash means not reported (the short form does not ask for employees or volunteers). Each figure links to that year's return. A year is left out when no return is in the IRS e-file data; that does not mean the group was inactive.

Revenue trend: Growing. Revenue went from $302,386 (year ending Sep 2021) to $897,953 (Sep 2025), about +31% a year.

Growth label: we compare total revenue on the oldest and the newest return shown above. Growing means revenue rose by more than 10% a year on average, Shrinking means it fell by more than 10% a year, and Steady means a change between -10% and +10% a year. The rate is the compounded yearly average between the two returns, so it hides ups and downs in between (see the table). We only label groups with returns at least a year apart and at least $5,000 of revenue on the oldest one. This is our own calculation, not an IRS rating or a judgment of quality.
